XBRL-based structured digital financial reporting - Blog: Digital Financial Reporting (using XBRL)

Foreign issuers submit XBRL-based reports to the U.S. Securities and Exchange Commission (SEC) that use the IFRS reporting scheme. I have put together several resources that help you understand IFRS reports created using XBRL, the IFRS XBRL Taxonomy, and XBRL-based reports in general.

451 reports: This is simply a flat list of reports, information about the reports, and links to resources that help you understand the reports. All of these reports use IFRS and are the annual reports (20-F, 40-F).
Information Extraction Tool: This is a ZIP file that contains a number of Excel applications that can be used to extract information from XBRL-based reports that use the IFRS XBRL Taxonomy.
Taxonomy Information: This is a viewer that lets you look at the XBRL presentation relations of each of the 451 XBRL-based reports created using the IFRS reporting scheme.
Model structure extractor: This is a ZIP file that contains an Excel spreadsheet application that lets you extract the XBRL presentation relations information from an XML Infoset which was generated for each of the 451 entiries that report using IFRS.
Concepts used to create report: This is a ZIP file that contains an Excel spreadsheet. The Excel spreadsheet has a summary of the 110,208 concepts used to create the 451 reports. Note that 97,722 of the concepts (or 88% of the total concepts) that were used in the 451 filings were used only once and virtually all of those were extension concepts. 263 were not extension concepts.
Tool for extracting information and understanding reporting styles: This is a tool for extracting information from IFRS XBRL-based financial reports, an explanation of reporting styles, and confirmed report errors.
Confirmed errors in IFRS reports: This is an analysis of the confirmed errors found for one specific reporting style.
More information for last year: This is information about other IFRS reports that I have analyzed earlier.

This information can help you create better XBRL-based reports in general and are specifically helpful in creating IFRS financial reports using XBRL.
